Abstract

The present invention relates to a coil arrangement for use in an inductive charging device, comprising a primary coil unit having a first number of primary windings arranged in a primary plane and secondary coil unit having a second number of coil windings substantially arranged in a secondary plane, wherein said primary plane and said secondary plane are arranged substantially in parallel, wherein said primary coil unit and said secondary coil unit are movable relative to each other, and wherein at least one of said primary winding has an opposite winding direction than the other primary windings and/or at least one of said secondary windings has an opposite winding direction than the other secondary windings. Further, the present invention relates to an inductive charging unit.
